HAND VISE;

Application filed October 16, 1922. Serial 115394.708.

To all whom it may ooficern:

Be it known that I, MAX CHRISTIAN 7 .ZANGE, .a citizen of the'United' States of America, and a resident of Cincinnati, in

the county of Hamilton and State of Ohio,

have invented a certain new and useful Im- I provement in Hand Vises, of which the 'following is aspecification.

This invention relates "hand-chucks used by mechanics and others to hand-.vises. or

in conveniently holding and handling small pieces or narrow lengths of material in connection with bench-vise, bench-'anvil ;and

. other similar hand-manipulated work, and

the peculiar structure of the invention, in-' cluding its objectsand advantages, claimed by me herein, are minutely, and fully described in connection withthe accompany proved hand-implement; embodying my invention and showing in clamped-position sheet of drawings, in which- "Figure 1 1s a frontelevation of the imtherein an elongatedv round-section piece or strip of wor -material 'ready for ma-' hipulat-ion' in connection with a bench-vise,

anvil, block, or other suitable base or resting-surface, and thus facilitating the use of a shaping-hammer, or of a dressing or finishing. file or other tool customarily ,used in n1ach1nists or' other mechanics' work, Fig. 2, an upper end i Yview of the said implement and its clamped.

work-piece, the latter being shown in cross- .section, for clearness; Fig. 3, a'left-side 'elevation of the implement-seen in Fig. 1;

Fig. 4, an elevation, similar to Fig. 1, .but

.made partly in section, the sectional parts being of the amb or thumb: nut and one end located at the upper end ofthe jaw carriermembers, and, also, oft ejawcarrier, spreader and a'w-closure device lo-, cated. 'atthe lower part- "of the implement,

and-including one of the upright wing or" of the spanner draw-bolt and its side-bars side-plate extensions on thesp're'ader sup porting-sleeve for" adjustably-coupling the lower ends of the said jaw" carrier-members;

' Fig.

'5', aftransverse section taken on the 7 horizontal dotted-line 4,4, of Fig. '4, to

more clearly show the spanner draw-bolt at the upper part of the assembled jaw carrier-members; and Fig. 6, a verticah central or' axial section of the implement, but with the lower jaw -closure or wedge device and its manipulating-head in'elevation, and, also,

air of- 7 and 8 together indicate a pa'ir'of correspondlng main jaw carrier-members, the

earner-member 7 being the movable one of the pair in correlation to the other carriermember 8 in so far as the opening of the upper grip or clamp jaws proper 9 and 10 are concerned, for holding-engagement with the work, the parts 11 and 12 indicating, respectively, the shanks or body-portions of the said'jaw carrier-members 7 and 8, and

composed of flat bars that have the broad; ened or transversely-extended grip or clamp aws proper 9 and 10 at their respective upper ends, circular enlarged openings or holes 13 near their lower ends, and 'trans verse fiatly recessed orfl countersunk portions 14, the latter producedon both sides of the shanks, clear across the face or width therepivotally-connected to the carriermember '8'by means ofthe .rivet 18. The

spanner or forked bars or plates 15 and 16 thatextendfrom thethreaded bolt-end 17 are'flat ones about half their lengths,but are round the balance oftheir lengths 'for the'provision o f a screw-thread 19 of sufficient length'to' accommodate the jamb or thumb nut 20 a. suitable distance along it fo the desired. closing ofxthe grip-jaws proper 9 and 10 on the very thinnest work as well as for any variegated .work that is expected to be placed or inserted in the implemntior; file andother service.

It will be readilyseen, in a. number of views of the drawing, that the fiat counter sunk-portions 14 are'somewhat 'wider than the width of the spaced spanner bars 15 and 16 of the split orforkeddraw-bolt 17 ,and, more especially, the countersink 14 on the two flat faces of the movable jaw carriermember 7, so that due allowance is thereby made for the swinging-movement of I the said movable carrier-member 7 to and from closed clamping engagement-with the work between the said grip-jaws proper 9 and 10.

The inner faces of the said grip or It willbeseen, too, and very particularly so in the successful carrying out of the important object and quite essential feature of my invention herein,-which is that of a clear and absolutely unobstructed broad passageway throughout the longitudinal center or axis and beyond both ends of the. entire implement herein, that the said draw-bolt spanner bars or plates-l5 and 16 are located at both sides of the central passageway, atrightangles to the inner edges of both of the jaw-shanks 11 and 12. Besides, the circular openings or holes 13-in the lower ends of the said j aw-sha-nks are somewhat enlarged beyond that. of the diameter or sectional area of the rivets 21 that I will now refer to more directly I in connection with the internallythreaded ringor sleeve 22 that has a pair of duly corresponding upright wings or sideplate extensions 23and'24 which each have holes pierced therein about 1 midheight for accommodating the said rivets 21. The rivets 21 extend through the wings 23 and 24 and through the said enlargedholes 13 in the jaw-shanks, but the wings are-not drawn "so tightly together as to preve'nt the jawshanks having a free sliding-movement between them to compensate for the 1 adj ustment of the movable jaw carrier-member 7 in relation to the companion jaw carriermember 8 for the proper closing of the grip jaws proper 9 and 10 on the work, no matter how thick or how thin thelatter might be, consistent with the range or capacity of the tool or implement herein, and to provide an adjustment of the: jaws that is parallel to that of the longitudinal:surfaceof the work 25 for use in forcibly turning the latter into spreading-engagement with the said beveled lower ends of the aw-shanks and, also, for

readily releasing the jaw-members from the "workwhen service on the latter has'been completed, or it is otherwise desired to change the position of the work in the implement. A series of holes or orifices 29 is provided in the 'saidknurled lower head or handle of" the wedge 25 for the special purpose of extratightening of the grip-jaw members on the work when required, and

which quite often occurs on short pieces, or on undue thick or thin ones, or on those having peculiar 0r lrregular surfaces.

In operating-the implement, the work or piece of material A, that may be an elongated strip or piece of round cross-section metal, as-shown, or it-may be a short one of other cross-section, or it' may be a strip of "wire, as the case may be, is inserted between the jaw-members 9 and 10' while the latter are in open condition, of course, with the opposite ends of the work extended beyond the oposite ends of the implement without any hindrance or obstruction whatever and as its length, that may be varied, maybe best served or accommodated; then the gripjaw members proper 9 and (10 are both brought into easy close touching-contact with the said strip of workby simplyturning the jamb or thumb nut20 forward along the threaded-portion of the outer unitingeend ordraw-bolt 17 of-the spanner-barsl5 and 16--until-the inner face of said 'jamb or thumb nut just touches or contacts easily with the outer face of the upright movable jaw-shank '11, wherebythe latter ismoved forward and i just lightly causes the gripjaw proper 9 to engagethework and force it just as lightly into contacting-engagement with the companion grip-j aw proper 10; and then the wedge or spreadermember 25 is turned upward or forward within the sleeve 22, using the lower head or handle 28, in forcibly doing so, until the lower beveled or tapered ends of the j aw-shanks 11 and 12 are spread outwardly so as to simultaneously close the said grip-jaws proper :9 and 10 into final tight-contact with the work, ready for active service on the -latter, -as desired. -The pivotal-movement of the movable gripj aw member 7 as well as what pivotal-movement there is inthe'lowerend of.the companion jaw-shank 12, is an important one at this juncture, for the reason that it provides firm hold or grip on the said-work-to prevent its slipping or shifting many or either direction while mounted in'the implement herein.

The jaw-shanksandthe balance of the implement below the jamb or thumbhnutform a handy, as well as comfortable, handgrasp in the use thereof wherever that-may be.

I claim:

In a work-holding hand-vise or 1 handchuck implement, the combination of a pair of aw carrier-members having 1 enlarged openings in the lower tapered ends of their shanks or body-portions, transversely-elongated gripsjaws provided at the upper: ends of-thesaid jaw carrier-members, an :open

split-ended,draw-bolt adapted to span the upper ends of the-said carrier-members beneath said grip-jaws and'to be l-pivotallyconnected at its outer split endto the ad--- j acent jaw carrier-member, a thumb-nut mounted on the threaded closed end of said draw-bolt and adapted to initially close the grip-jaws on the work that is extended downwardly through the implement in an unobstructed straight axial manner or passage from end to end thereof and beyond both ends as ma be required, an internallythreaded sleeve aving a pair of spaced upright side-Wings and adjustably-connected to the lower ends of the said jaw-carrier shanks by means of pins or the like that extend through and engage the said enlarged openings in the jaw-carrier shanks,

and an externally-threaded spreader having a Wedge-shape upper end for expandingengagement With the said lower tapered en s of the jaw-carrier shanks and, also, for,

engagement with the said internallythreaded sleeve, and, also, having a manipulating-head at the outer end of said spreader or expander for use in turning thelatter in opposite directions for the final tight gripping of the jaws on the work and permitting their release, respectively, substantially as herein shown and described.

MAX CHRISTIAN ZANGE.
